i Application led August 14, 1908. Serial No. 448,570.

To all whom 'it may concern:

Be it known that I, CHARLES'BALLREICH, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Lawn-Sprinklers, of .whichthe following is a specification.

This invention relates to lawn sprinklers, and its objects are to roduce a simple, compact and easily 'handled device having the advantages hereinafter described.

It embodies a spraying head or nozzle of peculiar shape and construction, whereby the watermay be distributed more evenly and more accurately than with the nozzles in common use, and inwhich the direction of thespray may be accurately controlled.

The novel features will be apparent from the following description taken in connection with the' drawing.

In the accompanying'"dravinga-Figue l is a perspective view showing my sprinkler in use on a lawn; Fig. 2 is a plan View v of the sprinkler head; and Fig. 3 is a section of the sprinkler head taken on the line 3--3 of Fig. 2; and Fig. 4 is a plan view of my device 1n operation, showing the limit of the spray discharged by it.

As shown in the drawings,

perforate bottom plate l, the imperforate vert-ical rear end plate 2s and the curved plate 3, which is provided with the perforations 4 arranged radially therein. A coupling piece for the water supply pipe is secured in a hole'in the plate 2.

It will be observed that the sprinkler head as thus formed is in the shape of a quarter of a sphere, '40

the dischar e perforations for the water being arranged in the curved part and being radial, thus discharging the water evenly and accuratelyin advance of a line across the device. In other words when the i' bottom platel is placed upon the ground the water is sprayed evenly upwardl and forwardly and to the right andle t, but` not rearwardly, and therefore it is possible for theuser to approach the sprinklerfrom'the rear without having the wa-terd'ischarged on him. Y Y

It is also possible to place the sprinkler against the side of the house or other object` and thus sprinklethe grass without having any water discharged .on

my *sprinklerembodies a closed head made up of the imin the windows. Alsothe sprinkler may be placed on the edge of the parking so as to sprinkle forward and to the right and left but not back on the sidewalk. This enables one to sprinkle along the sidewalk without wetting 1t or the persons passing along it.

It is a well-known fact that the. continued sprinkling of the side of a brick or stom` house discolors it up to the height of the spraying and also washes the mortar from between the bricks or stone, and in the case of frame houses the base boards are discolored and made' to rot.

My invention has the advantage of avoiding these objections which are incident to the use of the ordinary sprinkler.

IVhile I prefer to make the sprinkler head in the form of a quarter of a sphere, it is of course apparent that the curvature of the perforated plate need notl be that of a sphere and may be of less extent than a quarter of a sphere.

Changes may be made in the particular I shape so long as the perforations direct the water in substantially radial lines upwardly and forwardly.

In addition to its adaptability for use upon the ground my sprinkler may of course be used as a hand sprinkler. I prefer to make the s rinkler head of sheet brass pressed into orm, but it will be understood that any other suitable metal or material maybe used in making itu- Having thus described the invent-ion, what is claimed is y l. A lawn sprinkler embodying a hollow closed head having a fiat bottom, and upright rear wall and ai spheroidal upper portion', the inclination of which is downward from theA rear wall, the said head being provided With an inlet in the rear \vall and the said upper portion only being provided with radial perforations.

'2. A lawn'sprinkler embodying a hollow closed head in the shape ofa quarter of a sphere rovided with an inlet for water and Awith discharge perforations in the curved portion only.

In testimon whereof I aix my signature in presence o two witnesses.
